Grain Size Effects in Selective Laser Melted Fe-Co-2V

Webunderlying theory, it is also more readily explicable. It is concluded that the Hall-Petch effect is not to be explained by the variety of theories found in the literature, but is a manifestation of, or underlain by, the general size effect observed throughout micromechanics, due to the inverse relationship between the stress required and the space WebThe current study reveals the Hall-Petch relationship, or mean grain size control, and flow properties of equiatomic FeCoNi alloy having different grain sizes at room temperature (298 K) and cryogenic temperature (77 K). For the first time, various mean grain sizes ranging from the ultra-fine regime (0.7 μm) to the coarse grain regime (145.3 ... newton north high school staff

As detailed in Table IV and in Fig. 4 , at a higher molarity of 0.5M, the grain size decreased as the oxide source ratio decreased and the dopant source ratio increased in precursor solutions. midwest snack foods
